JAMES A. CAMERON AND GUSTAF BIRGER BIRCH, 0F BROOKLYN, NEW YORK, ASSIGN- ORS TO CAMERON MACHINE COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

SURGICAL BANDAGE.

To all whom it may concern.

Be it known that we, JAMES A. CAMERON and GUSTAF B. BIRCH, both citizens of the United States, and residents of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Surgical Bandages, of which the following is a specification.

This invention relates to surgical bandages in general and more particularly to bandages that are sold to the trade in the form of rolls composed of single strips of material of desirable ,width.

It is well known that the material of which bandages are made is usually of an open mesh character so that the warp threads adjacent the edges of the bandage strip have a tendency to ravel from the bandage. This is objectionable for the reason that it interferes with the work of the surgeon by entangling his fingers as he applies the bandage. In order to prevent this objectionable unraveling of the outermost warp threads, it is customaryin the art to remove a number of such threads from each end of the bandage roll. This results in a considerable waste and an object of this invention is to substantially reduce the amount of such waste.

The surgeons bandage constituting this invention is severed from the web of material with an undulating cut so as to simultaneously destroy the continuity of the warp threads adjacent to the cut and so as to leave a scalloped edge formed by weft threads of unequal length. The bandage is consequently of such a character that the edges thereof will not unravel since the outermost warp threads are destroyed and the remaining warp threads are held in place by the scalloped edge formed by the weftthreads of unequal length recurring at regular intervals. I

In the drawing:

Figure 1 shows the undulating line of severance by which bandages embodying the invention are cut from the web of material.

Fig. 2 shows the effect of theundulating cut with the severed warp threads still in place.

warp threads removed.

Specification of Letters Patent.

Patented Feb. 27, 1917.

Application filed March 3, 1916. Serial No. 81,810.

Surgeons bandages are ordinarily made of soft, loose-textured fabric the edges of which are easily unraveled unless precau tions are taken to prevent it. In this invention a web of bandage material, indicated at 1,.is severed by means of an undulating cut as at 2 whereby scalloped edges are formed by weft threads 3 of unequal length int-ermeshed with fragments of the severed warp threads 4 as is best shown in Fig. 2. The removal of the severed warp threads 4 leaves a scalloped edge formed of the remaining weft threads 3 alone which constitutes the finished article shown in Fig. 3.

By thus providing an edge composed of weft threads from which a number of warp threads have been removed, the tendency of the edges to ravel is overcome. By, in effect, causing convex portions of the edge of one strip to project into concave portions of the edge of a contiguous strip in alternation, the total number of threads which it is necessary to remove from the edges of the strip to prevent unraveling is diminishedby one half.

The improved bandage strip can be quickly and cheaply made and is more sightly in appearance than bandages now in use not only because of the lessened amount of material in the projecting weft threads, but also because of the regular arrangement of the varying lengths of projecting threads.

What is claimed, is:

1. A surgeons bandage comprising: a strip of material the edges of which are scalloped and formed by weft threads of unequal length recurring at regular interscalloped and the convex portions of which are formed of weft threads.

strip of material the edges of which are scalloped and the convex portions of which are composed of Weft threads from Which the Warp threads have been removed.

6. A surgeons bandage comprising: a strip of material the longitudinal edge threads of Which have been removed, and the transverse edge threads of which present an undulating edge.

7. A surgeons bandage having undulating side edges devoid of longitudinal threads.

8. A surgeons bandage having side edges composed solely of unequally projecting 15 weft threads recurring at regular intervals.
